The weather will be in the mid 80's during the day, although you may want a light jacket or sweater at night.
We've sailed the Caribbean in Jan and March..neither time was the ship "empty". Just keep in mind, most of them are so big....2000 people doesn't create a crowd. ENJOY!!! [img]/infopop/emoticons/icon_cool.gif[/img]

I think it's pretty safe to say you'll have temps about 80 during the day. We went on a Caribbean cruise in March 2001 on Dawn Princess. For the 2 weeks before our cruise, they said temps got down into the high 60's, due to a massive front that came down and took in Florida and most of the Caribbean. You'll get these odd things. Bring a sweater and lightweight jacket and you should be OK. Happy sailing! [img]/infopop/emoticons/icon_wink.gif[/img]
Forgot to mention, ship will not be crowded with children, as most will be back to school. Can't say the same for March or April Sprin break.
